We are facing an issue with the Polycom VVX 600 phones on Lync.
IF you put a call on hold , the phone changed the ptime to 80 in the invite, causing issues with our provider ( does not allow ptime > 30).
I can not find a parameter to manipulate this value. Is this somehow possible ?
We are running on 5.3.0 firmware.
Solved! Go to Solution.

Hello Bart,
welcome to the Polycom Community.
The Software that you are using is no longer supported as we always only support current GA -1 aka 5.4.4 or 5.4.3
If you are bound to use the 5.3.x release please upgrade at least to 5.3.3
Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

I can not upgrade because it will not work on our network ( voice-vlan + 802.1x -> upgrade always fails ... )
I just tried with one phone on 5.4.4 -> same issue, so not related to firmware. I could also not find anything in the release notes regarding ptime.
Very annoying problem offcourse because nobody using a Polycom phone can place a call on hold or transfer.
Other phones (other vendor) work fine , same as Lync softclient). All use the same MOH wav file.

Hello Bart,
to my knowledge we only have a PTime parameter for the Opus codec.
Have you yet worked with a Polycom reseller or can you send me a MAC address from a VVX and your details via community mail so I can get an Polycom SE to contact you in your region?

you can set the timer for each codec :
Payload Size (ms)
And it is set to 20 for all , but when you enable MOH , MOH uses ptime:80 ( 80ms).
SDP info :
a=sendonly
a=rtpmap:8 PCMA/8000
a=rtpmap:127 telephone-event/8000
a=ptime:80
